Measures to Improve Dust Removal Effect of Crusher Dust Collectors

Crusher dust collectors often have poor dust removal effects due to high dust concentration and strong abrasiveness. 

The following six measures can effectively improve the effect:

1. Check and maintain filter bags: 

Replace damaged, aged, or blocked filter bags in a timely manner; ensure the bags are installed firmly (no air leakage). For strong abrasiveness, use wear-resistant bags (e.g., FMS) and replace them regularly.

2. Optimize cleaning parameters: 

Increase the pulse cleaning frequency (from 30-60s/time to 20-40s/time) and appropriately increase the cleaning pressure (to 0.5-0.6MPa) to ensure thorough cleaning of dust on the bag surface.

3. Strengthen equipment sealing:

 Check the access door, flue gas inlet/outlet, and ash discharge device for air leakage; replace aging seals (e.g., rubber gaskets) and tighten loose bolts to avoid unfiltered dust bypassing.

4. Match fan air volume and pressure: 

Check whether the fan’s air volume and pressure are sufficient; if not, replace the fan or adjust the fan speed to ensure the air volume meets the crusher’s dust generation demand.

5. Add pre-treatment devices:

 Install a cyclone dust collector at the inlet of the crusher dust collector to remove large-particle dust (≥10μm) in advance, reducing the load on the filter bag and avoiding scratch damage.

6. Clean regularly: 

Clean the ash hopper, flue gas pipeline, and fan impeller regularly to avoid dust accumulation and blockage, which affects air circulation and dust removal efficiency.
